ABS Plastic Injection Molding
ABS (Acrylonitrile Butadiene Styrene) is one of the most common thermoplastics used in injection molding. It provides a reliable mix of toughness, rigidity, and surface finish, making it suitable for both functional and decorative components.
Key Properties
- High impact strength
- Good rigidity and dimensional stability
- Smooth surface finish — ideal for paint or plating
- Heat deflection around 80–100°C
- Excellent processability and cost efficiency
Common Applications
ABS is used across consumer electronics, automotive trim, power tool housings, and equipment panels. Its durability and ease of finishing make it a go-to for product enclosures and prototypes.
Design Considerations
Keep wall thickness uniform (2–3.5 mm typical), provide 1° draft per side, and use ribs or gussets for stiffness. Avoid abrupt transitions that can cause stress whitening or sink marks.
Additives and Variants
UV-resistant, flame-retardant, and plating-grade versions are available.
Blends with polycarbonate improve impact and heat performance for demanding applications.
When to Choose ABS
Choose ABS when you need a balance of strength, appearance, and manufacturability.
